The number of oral cancers associated with Human Papillomavirus (HPV) infection is increasing worldwide. The purpose of this retrospective clinical trial is to investigate the relationship between genital and oral HPV infection and to observe the possibilities of polymerase chain reaction (PCR) technique and the limitations for oral HPV infection. The results of genital and oral HPV screening of 34 female patients and their partner, and 14 single female patients were processed in a private practice in Budapest between 2012 and 2015. After brush-biopsy sampling, HPV DNA identification and typing were performed using PCR technique. All in all 164 samples were typed. HPV DNA was detected in 76 cases (48.20%). HPV was detected in 55 cases from the genital samples (67%), and in 21 cases from the oral samples (25.6%). Genital HPV infection was statistically significantly higher in women (79.2% vs 22,9%, p[0.001). Gender comparison of genital HPV infection showed a statistically significant difference (79.2% for women, 50% for men, p = 0.006). In case of genital HPV infection, the oral HPV infection of the same person is more frequent. In this study, the above mentioned difference is significant for women and not significant for men. HPV16 is the HPV genotype which was identified in the highest ratio(47.2%). PCR technique is capable of the detection of oral HPV infection, but follow-up studies with higher case number , and questionnaire studies are needed to understand HPV transmission more accurately.

Introduction: Human papillomavirus (HPV) is frequently a sexually transmitted virus and can cause cervical cancer in women. Cervical cancer is the second most common type of cancer among the developing countries. In this study, cervical HPV DNA positivity and genotype distributions were investigated in female patients living in our region and the results were compared with different studies. Materials and Methods: Between 1 July, 2017 and 1 March, 2019, 433 cervical swabs were sent to Ataturk University, Medical Faculty Hospital, Medical Microbiology Laboratory due to suspicion of HPV. Swab samples were evaluated for HPV virus using molecular (Polymerase Chain Reaction-PCR) methods. For this purpose, Xpert HPV Test (Cepheid, Inc, Sunnyvale, CA) was used to identify HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 t in a single sample. Results: Mean age of the patients ranged from 20 to 69 years, with a mean of 39.8 years (± 10.0). Positivity was detected in 62 of the 433 patients. Mean age of the positive patients was 40.2 years (± 11.3). When the positive patients were examined in terms of HPV types, the presence of HPV 16 was observed with a rate of 25.6%, while the HPV 18/45 types were found to be 9.0% in total. When patients were evaluated according to age groups, HPV DNA positivity was highest in the 25-34 age group with 38.7%. In our statistical study, there was no significant difference in HPV DNA positivity rate between the ages of 35 and under 35 years. Conclusion: This study demonstrates the prevalence and viral genotype distribution of HPV infection in women in Erzurum region. HPV type 16 is seen with a high rate in our region.

A high-risk population, formed by 79 consecutive male attendees of our sexually transmissible infections clinic, and who did not have any overt signs of human papillomavirus (HPV) infection, were examined. Oral HPV prevalence (37%) was much higher than previously reported. Periurethral HPV-DNA was found in 49% of the patients and anal HPV-DNA was found in 43% of the patients. Considering the high prevalence of oral HPV obtained in the current study, it is important to further investigate the burden of oral HPV, not only in men who have sex with men, but also in heterosexual men and in women.

Objective. To determine the prevalence and risk factors for oral high-risk human papillomavirus (HR-HPV) infection in human immunodeficiency virus (HIV)-infected men. Materials and methods. Consecutive male outpatients with HIV-infection were enrolled. Demographic and behavioral risk data were obtained. Anal swabs and oral rinses were tested for HR-HPV DNA. Oral, pharyngeal and video laryngoscopy examinations were performed for detection of lesions. Results. The prevalence of HR-HPV oral infection was 9.3% (subtypes other than HR HPV 16/18 predominated). The prevalence of anal HR-HPV infection was 75.7%. The risk factors for oral infection with HR-HPV were tonsillectomy (OR=13.12) and years from HIV diagnosis (OR=1.17). Conclusions. Tonsillectomy and years from HIV diagnosis were associated with oral HPV infection. No association was found between oral and anal HR-HPV infections. This is the first study reporting the prevalence and risk factors for oral HR-HPV infection in Mexican HIV-infected population.

Abstract Background: Despite the demonstrated role of human Papillomavirus (HPV) in the etiology of cervical cancer and the strong evidence suggesting the importance of HPV in the development of oropharyngeal cancer, several aspects concerning the interrelationship between HPV infection in both body sites remain unknown, specifically in human immunodeficiency virus (HIV)-positive (HIV+) female patients. We aimed to assess the prevalence, distribution, and concordance of cervical and oral HPV in HIV+ women and matched HIV-negative (HIV-) controls in Brazil. Material and methods: Cervical and endocervical samples for cytological screening and HPV detection and oral samples were collected from 115 HIV+ women using highly active antiretroviral therapy (HAART) and 139 HIV-matched controls (HIV-) in Maringá City, Brazil. Risk factors were assessed using a standardized questionnaire, and the data regarding HIV infection were obtained from the patients’ medical records. HPV detection and typing were performed using the Kit Multiplex XGEN Multi HPV Chip HS12. Results: HIV infection was well controlled in this cohort, but women who exhibited detectable HIV load were significantly associated with HPV-positive status in overall (P = 0.03) and in cervical mucosa (P = 0.01). HIV+ women had significantly more abnormal cytological findings (P = 0.04) than HIV- women. Of the 115 HIV+ women, 48.7% were positive for cervical and/or oral HPV DNA; of the 139 HIV- women, 41% were positive for cervical and/or oral HPV (P = 0.25). Both HIV+ and HIV- women had a statistically higher prevalence of cervical HPV infection than oral infection. The concurrent HPV infection in two anatomical sites was similar in HIV+ and HIV- women, however HPV type concordance was not observed. HPV type distribution was different between the anatomical sites in both groups, and HIV+ women presented less common types, mainly in oral mucosa. Conclusion: Our data support the importance of HPV infection in HIV+ women, even when the HIV infection is well controlled. Prospective studies are required to better understand the natural history of HPV infection in both anatomical sites, specifically in HIV+ women.

Purpose To better understand oral human papillomavirus (HPV) infection and cancer risk among long-term sexual partners of patients with HPV-positive oropharyngeal cancer (HPV-OPC). Patients and Methods An oral rinse sample, risk factor survey, cancer history, and oral examination (partners only) were collected from patients with HPV-OPC and their partners. Oral rinse samples were evaluated for 36 types of HPV DNA using PGMY 09/11 primers and line-blot hybridization and HPV16 copy number using quantitative polymerase chain reaction. Oral HPV prevalence was compared with infection among those age 45 to 65 years using National Health and Nutrition Examination Survey (NHANES) 2009-2010. Results A total of 164 patients with HPV-OPC and 93 of their partners were enrolled. Patients were primarily men (90%), were never-smokers (51%), and had performed oral sex (97%), with a median age of 56 years; they had a high prevalence of oncogenic oral HPV DNA (61%) and oral HPV16 DNA (54%) at enrollment. Female partners had comparable oncogenic oral HPV prevalence compared with members of the general population of the same age (1.2% v 1.3%). Among the six male partners, no oncogenic oral HPV infections were detected. No precancers or cancers were identified during partner oral cancer screening examinations. However, a history of cervical disease was reported by nine partners (10.3%) and two female patients (11.8%), and three patients (2.0%) reported a previous partner who developed invasive cervical cancer. Conclusion Oral HPV16 DNA is commonly detected among patients with HPV-OPC at diagnosis, but not among their partners. Partners of patients with HPV-OPC do not seem to have elevated oral HPV infection compared with the general population.

The main goal of this study was to investigate, through a biomolecular study, the correlation between papillomatosis of the vulvar vestibule and human papillomavirus (HPV) infection, as well as to establish the necessity of treatment. A total of 44 female adolescents between 12 and 18 years of age were selected through a prospective study with a confirmed diagnosis of papillomatosis of the vulvar vestibule. Vulvar biopsies were obtained for the histological and biomolecular detection of HPV DNA through polymerase chain reaction (PCR). Twenty (45%) adolescents were virgins (group A), the other 24 (55%) were sexually active. The virgin adolescents (group A) and 12 sexually active adolescents (group B) did not show cytological and/or colposcopic alteration, suggesting infection by HPV either on the cervix or vagina. These were compared with 12 other sexually active adolescents who showed cervicovaginal infection caused by HPV (group C). Fisher exact test was applied for statistical analysis of the results, considering alpha equal or less than 0.05. There was no statistically significant difference in relation to HPV DNA through PCR among virgin and sexually active adolescents in group B, however, both differed from those in group C (A + B × C:p= 0.048*). The histological study did not reveal evident signs of infection caused by HPV on vestibular papillae, besides perinuclear halos. HPV DNA was detected on vestibular papillae in 27%. Our results confirmed a scarce correlation between vestibular papillae and HPV. Thus, we consider papillomatosis of the vulvar vestibule, in most cases, to be equivalent to physiological papillomatosis and, therefore, should not be treated.

Abstract Background Data about the genotype-specific human papillomavirus (HPV) prevalence in the Czech Republic is limited. We aimed to evaluate the prevalence and concordance of genotype-specific HPV infection detected in semen samples, penile swabs and cervical swabs from non-vaccinated heterosexual couples without HPV-associated disease. Methods Semen samples and penile swabs were collected from male partners and cervical swabs were collected from female partners of heterosexual couples treated for infertility (n = 195). Presence of HPV DNA in semen samples and cervical swabs was analyzed using the cobas® HPV Test and PapilloCheck®. Only the PapilloCheck® test was used to detect HPV in penile swabs. The genotype-specific prevalence and concordance of HPV infection not targeted by vaccine were evaluated using Fisher exact test. Results Both partners were infected with any HPV type in 13.8% (27/195) of couples and, of these couples, 55.6% (15/27) harbored at least one mutual genotype. High-risk HPV (hrHPV) genotypes were detected in 12.3% (24/195) of semen samples, 31.3% (61/195) of penile swabs, and 19.5% (38/195) of cervical swabs (P < 0.001). The most prevalent hrHPV genotype were HPV53 (2.56%; 5/195) in semen samples, HPV16 (6.67%, 13/195) in penile swabs and HPV39 (3.59%, 7/195) in cervical swabs. Low-risk (lrHPV) genotypes were detected in 5.13% (10/195) of semen samples, 15.9% (31/195) of penile swabs, and 4.10% (8/195) of cervical swabs (P < 0.001). Male sexual partners of HPV-positive women were more likely to be infected with at least one of the same HPV types than female sexual partners of HPV-positive men (34.9% vs. 17.9%, P = 0.055). Conclusions This study showed that the detection of HPV infection differ by anatomic site and gender. Regardless the anatomic site, high prevalence of HPV genital infection was found in both Czech men and women.

AbstractHost cell DNA methylation analysis in urine provides promising triage markers for women diagnosed with a high-risk (HR) human papillomavirus (HPV) infection. In this study, we have investigated a panel of six host cell methylation markers (GHSR, SST, ZIC1, ASCL1, LHX8, ST6GALNAC5) in cervicovaginal secretions collected within the first part of the urine void (FVU) from a referral population. Cytology, histology, and HPV DNA genotyping results on paired FVU and cervical samples were available. Urinary median methylation levels from HR-HPV (n = 93) positive women were found to increase for all markers with severity of underlying disease. Significantly elevated levels were observed for GHSR and LHX8 in relation to high-grade cervical intraepithelial neoplasia (CIN2 +; n = 33), with area under de curve values of 0.80 (95% Confidence Interval (CI) 0.59–0.92) and 0.76 (95% CI 0.58–0.89), respectively. These findings are the first to support the assertion that methylation analysis of host cell genes is feasible in FVU and holds promise as molecular, triage strategy to discern low- from high-grade cervical disease in HR-HPV positive women. Molecular testing on FVU may serve to increase cervical cancer screening attendance in hard-to-reach populations whilst reducing loss to follow-up and await further optimization and validation studies.

Potential Risk Factors

It is crucial to understand the natural history of genital human papillomavirus (HPV) infection in men to prevent the increasing male HPV-related disease burden. We evaluated the associations between HPV infection and circumcision, smoking, and alcohol use after accounting for sexual behavior. The study included 2331 male personnel from Danish barracks. Penile swabs were tested for HPV DNA with a polymerase chain reaction assay, INNO-LiPA. All men completed a self-administered questionnaire providing data on potential risk factors for HPV such as lifestyle and sexual habits. Using multivariable logistic regression, associations between potential risk factors and HPV infection were estimated and expressed as odds ratios (ORs) with 95% confidence intervals (CI). Current cigarette smoking was associated with increased odds of HPV detection (OR = 1.2; 95% CI: 1.0–1.4), but we found no association with alcohol use in the analysis adjusted for sexual behavior. Circumcision reduced the odds of a prevalent HPV infection (OR = 0.7; 95% CI: 0.5–1.0) although not statistically significantly. Strong associations with lifetime and recent number of female sex partners were observed, but in contrast to uncircumcised men, increasing number of sex partners was not associated with higher HPV prevalence in circumcised men. In conclusion, smoking was associated with increased odds of penile HPV in men from the general population in Denmark, whereas circumcision seemed to reduce the risk. Moreover, our results indicated that there might be differences in the viral susceptibility between circumcised and uncircumcised men.

Exfoliated Cells

We evaluated the detection of human papillomavirus (HPV) infection using two sampling methods of cervical exfoliated cells, consisting of self-sampling of vaginal cells and cervical sampling performed by the physician. Women included were 379 patients of the general population attending outpatient clinics in Northern Greece for routine cytological cervical dysplasia screening. HPV DNA detection was similar with both sampling techniques. The HPV prevalences in self-collected samples were 4.7% and 3.7% in the physician-collected samples ( P>0.05). The Kappa statistic for HPV DNA agreement between the two methods was 0.54 (95% Confidence interval = 0.33–0.75). Self-sampling of cervico-vaginal exfoliated cells could be used as an alternative option to test for HPV infection.
